Abstract

A battery information compression apparatus according to an embodiment of the present disclosure includes a battery information obtaining unit obtaining battery information for each of a plurality of batteries; and a communication code generating unit determining a representative value for a plurality of battery information, calculating a reference value for each of the plurality of battery information based on the plurality of battery information and the representative value, determining a first encoding code corresponding to the representative value and a second encoding code corresponding to the plurality of determined reference values according to a preset encoding rule, and generating a communication code including the first encoding code and the second encoding code.

First claim

What is claimed is:

1. A battery information compression apparatus, comprising:
a battery information obtaining unit configured to obtain battery information for each of a plurality of batteries; and
a communication code generating unit configured to determine a representative value for a plurality of battery information, calculate a reference value for each of the plurality of battery information based on the plurality of battery information and the representative value, determine a first encoding code corresponding to the representative value and a second encoding code corresponding to the plurality of calculated reference values according to a preset encoding rule, and generate a communication code including the first encoding code and the second encoding code.

2. The battery information compression apparatus according to claim 1 ,
wherein the communication code generating unit is configured to calculate a difference between battery information obtained at a first time point and battery information obtained at a current time point by the battery information obtaining unit for each of the plurality of batteries, and determine a minimum value among the plurality of calculated differences as the representative value, and
wherein the first time point is earlier than the current time point.

3. The battery information compression apparatus according to claim 2 ,
wherein the communication code generating unit is configured to calculate the reference value for each of the plurality of battery information by calculating a difference between each of the plurality of calculated differences and the representative value.

4. The battery information compression apparatus according to claim 1 ,
wherein the preset encoding rule includes a first encoding rule used to determine the first encoding code and a second encoding rule used to determine the second encoding code.

5. The battery information compression apparatus according to claim 4 ,
wherein the communication code generating unit is configured to determine a first header code and a first body code corresponding to the representative value according to the first encoding rule, and determine the first encoding code including the first header code and the first body code.

6. The battery information compression apparatus according to claim 4 ,
wherein the communication code generating unit is configured to determine a second header code corresponding to the plurality of reference values according to the second encoding rule, determine a second body code corresponding to each of the plurality of reference values according to the second encoding rule, and determine the second encoding code including the second header code and the plurality of second body codes.

7. The battery information compression apparatus according to claim 6 ,
wherein the communication code generating unit includes the plurality of determined second body codes in the second encoding code according to an alignment rule preset for each of the plurality of batteries.

8. The battery information compression apparatus according to claim 1 , further comprising:
a communication unit configured to output the communication code generated by the communication code generating unit to an external device.

9. A battery pack, comprising:
the battery information compression apparatus according to claim 1 .

10. An energy storage system, comprising:
the battery information compression apparatus according to claim 1 .

11. A battery information compression method, comprising:
obtaining, by a battery information obtaining unit, battery information for each of a plurality of batteries;
determining, by a communication code generating unit, a representative value for a plurality of battery information;
calculating, by the communication code generating unit, a reference value for each of the plurality of battery information based on the plurality of battery information and the representative value;
determining, by the communication code generating unit, a first encoding code corresponding to the representative value and a second encoding code corresponding to the plurality of calculated reference values according to a preset encoding rule; and
generating, by the communication code generating unit, a communication code including the first encoding code and the second encoding code.
